Tween (or polysorbate) is a non-ionic surfactant with an odor, warm and slightly bitter. It is a series of polyoxyethylene dehydrated sorbates. Partial fatty acid esters of alcohols. Widely used as emulsifier and solubilizer for oil substances. Since Tween is an ester formed of sorbitol and different higher fatty acids, Tween is actually a series of products of the same type. It is divided into 20, 40, 60, and 80 types in general fine chemical stores or chemical reagent companies. According to different Need to choose.
The specific uses of each Twain model are as follows:
1. Twain 20:
This product is harmless to the human body and has no irritation. It is mainly used in the food industry for making cakes, ice cream, shortening, etc.
In other aspects, it can be used as an emulsifier for mineral oil, a solvent for dyes, an emulsifier for cosmetics, a stabilizer for foam plastics, an emulsifier, diffusing agent and stabilizer for pharmaceuticals, and a photo emulsion. of additives.
2. Tween 40:
Mineral oil, used as o/w emulsifier, solubilizer, stabilizer, diffusing agent, and antistatic agents, lubricants.
3. Tween 60:
Used as o/w emulsifier, dispersant, stabilizer, used in food, medicine, cosmetics, Manufacturing of water-based coatings.
Used as a softener and antistatic agent in the textile industry. It is a component of polyacrylonitrile spinning oil and a softener for fiber post-processing. It can eliminate static electricity on the fiber, improve its softness and give the fiber Good dyeing properties.
4. Tween 80:
It is used as a stabilizer and assistant foaming agent in the production of polyurethane foam; it can be used as an anti-foaming agent in synthetic fibers. Static agent is an intermediate of chemical fiber oil. It is used as a wetting agent and dispersant in film films made of photosensitive materials. It is used to emulsify silicone oil in the fabric waterproofing process and has good results. It is also used in nylon and viscose cords. As an oil agent and water-soluble emulsifier, it is often mixed with S-80.
Used as oil field emulsifier, anti-wax agent, heavy oil wetting, resistance reducing agent, near-well zone treatment agent; used as precision machine tool preparation lubrication coolant, etc.
